Geography
Location
The Lodna Area office is located at. The Lodna Area is situated in the central area of Jharia coalfield and is 15 km south of Dhanbad Junction railway station. The Dhanbad-Sindri Road passes through the Area. The map alongside shows some of the collieries in the Area. However, as the collieries do not have individual pages, there are no links in the full screen map. In the map placed further down, all places marked in the map are linked in the larger full screen map.

It had an expected life of 30 years. 2. North Tisra colliery, with an underground mine, has a normative production capacity of 0.15 million tonnes per year and a peak production capacity of 0.195 million tonnes per year. It had an expected life of 30 years. 3. North Tisra-South Tisra colliery, with an open cast mine, has a normative production capacity of 1.65 million tonnes per year and a peak production capacity of 2.145 million tonnes per year. It had an expected life of 26 years. 4. Jealgora colliery is a closed mine. 5. Bagdigi colliery, with an underground mine, has a normative production capacity of 0.11 million tonnes per year and a peak production capacity of 0.143 million tonnes per year. It had an expected life of 30 years. 6. Joyrampur colliery, with an underground mine, has a normative production capacity of 0.153 million tonnes per year and a peak production capacity of 0.199 million tonnes per year. It had an expected life of 30 years. 7. Jeenagora colliery, with an open cast mine, has a normative production capacity of 0.7 million tonnes per year and a peak production capacity of 0.91 million tonnes per year. It had an expected life of 5 years. 8. Bararee colliery, with an underground mine, has a normative production capacity of 0.17 million tonnes per year and a peak production capacity of 0.221 million tonnes per year.
